John,
You HAVE to hire a local as a tour guide, that is the law. To be a tour guide the locals have to be certified as well thru the Govt. Belize does this so foriegners, such as us, do not come in here and self employee the locals out of jobs.
You can ask anyone who has been here, they love the local flavor when diving. Why come all this way to talk to another Canadian or American dive master, they want a local person with a fun attitude.
The B&B might be a different story not sure.
